I’ve used this shampoo after multiple colour treatments and noticed my hair stayed vibrant for much longer than expected. The texture is smooth and doesn’t leave my hair feeling dry. My colour looks fresh even after several washes.

It works well for maintaining my red hair tone. The protein content helps my hair feel stronger and less frizzy after washing. I still see a bit of fading after 6 weeks, but it’s better than other shampoos I’ve tried.

After switching from a regular shampoo, my hair feels healthier and the colour stays rich and full. I appreciate the pH balance that helps keep the cuticle closed.
